The House of Commons was placed on lockdown and Prime Minister Theresa May was seen being rushed away from the scene in a silver Jaguar.

At the moment, the very clear advice from the police and the director of security in the house is that we should remain under suspension, and that the chamber should remain in lockdown until we've received advice that it is safe to go back to normal procedures.

An air ambulance reported to the scene of the incident to help those who were injured.

There was also an incident on Westminster Bridge in which a car "mowed down at least 5 people," according to a witness.

According to BBC News, the car "deliberately" hit pedestrians, and this occurred roughly around the same time as the incident at Parliament.
